The "made in Japan" dates this Satsuma ware vase at least 1930's.
The Mount Fuji with stream above it looks like a Fukagawa mark, but it is not. Fukagawa didn't make Satsuma ware and certainly not this kind of decorations.
Probably made by a small family workshop, of which there were many in that period before WW2.
